Abstract
A method installs building control software. The method includes the transmission of an identity of a runtime environment from the runtime environment to a software delivery entity. A file is generated by the software delivery entity, wherein the file contains the transmitted identity and the software to be installed or a hash of the software to be installed. The generated file is signed by the software delivery entity by a key of the software delivery entity. The signed file is transmitted from the software delivery entity to the runtime environment. An installation and/or an authorization of the software to be installed in the runtime environment are performed, if and only if the identity of the runtime environment corresponds with the identity that has actually been transmitted in the signed file. Devices for installing the building control software are also discussed.
